XVINFIELD' S. BURGESS, OF MARATHON, NEW YORK.

AUTOMATIC LAMP-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 322,579, dated July 21,1885.

Application filed March 25, 1885. (No model.)

To all whom it may concern:

Be it known that I, WINFIELD S. BURGESS, of Marathon, in the county ofCortland and State of New York, have invented a new and ImprovedAutomatic Lamp-Extinguisher, of which the following is a full, clear,and exact description.

The object of my inventionis to providea new and improved automatic lamp-extinguisher for automatically extinguishing the flame at any desiredtime after the lamp has been lighted.

The invention consists in the combination, with the burner, of a cappivoted on the same, a rod for holding the cap from over the wicktube, aspring or weight acting on the cap, a float in the fount and devices forlocking the float to the rod at any desired elevation of the float abovethe bottom of the fount.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a lamp provided withmy improved extinguishing device, taken on the line or 00, Fig. 3. Fig.2 is a cross-sectional elevation of the same on theline 3' Fig. 3. Fig.3is a plan view of the same. Fig. at is a plan view of the float.

From. the bottom of the fount A the guiderods B project upward andthrough apertures C in a float, G, in the fount, which float has alarger central aperture, D, one edge of which is straight.

A wire bow spring, E, or other shaped spring, has its ends secured tothe straight edge of the aperture D in such a manner that the middleportion of the spring almost rests against the said edge.

A metal clip, F, provided with-a funnelshaped part, F, is held on thetop of the float in such a manner that the funnel projects beyond thestraight edge of the opening D.

A pin, G, having a head, G, projects upward from the float below thefilling-neck, G

A rod, H, passes through the burner and through the funnel F, the upperpart of the rod being round and the lower part, H, flattened. The upperpart of the rod H is graduated, as at a, and to the said upper part anangular handle-piece, J, is secured by means of which the rod can beturned. The upper end of the rod H rests against a guide-lug, K, on theside of the wick-tube L.

A flattened cap, M, is pivoted to the sides of the wick-tube in such amanner that it can swing over the top of the wick-tube and cover thesame. A lug, N, projects from the side of the cap at the edge. 4

A lever, O, is pivoted in the burner-frame or shell and has a weight, P,on the outer end, the inner end forming a lengthened loop, B, throughwhich a pin, Q, passes, which pro.- jects from the sideof the cap;

Instead of providing the loop, the inner end of the lever 0 may beslotted.

A spring may be provided to act on the cap. in place of the weight andlever.

The other parts of the burner are of the usual construction.

The operation is as follows: The rod H is pulled upward until the lug Non the cap M is at the desired mark or graduation on the rod, as shownin Fig. 1, whereby the cap is held off the wick-tube, and the weight 1?is raised. The handle-piece J is then parallel with the wick-tube, andthe flat portion H of the rod H is at right angles to the straight edgeof the opening D. The handle-piece J is then brought into a position atright angles with the wick-tube, whereby the flat portion H of the rod His brought into a position parallel with the straight edge of theopening D, and is forced againstthespring E, as shown in Fig. 4, andwhereby the rod is held fixed to the float and must rise and descendwith the same.

When the flat portion H of the bar H is parallel with the straight edgeof the opening D, the rod can be moved up and down freely between thespring E and the straight edge of the aperture.

\Vhen the rod vH is locked to the float, it descends with the float, andwhen its upper end passes under the lug N on the cap M the said cap isreleased and swung by the weight P in the direction of the arrow a andover the top of the wick-tube, thus extinguishing the light. The devicecan-be adjusted to extinguish the light after any desired time.

\Vhen the upper end of the rod projects a greater distance above the lugN, the light will burn a longer time before it is extinguished? It isimmaterial how full the fount is, as the rod H and float O can be lockedtogether at any time and independent of the height of the float abovethe bottom of the fount.

When the fount is being filled, the pin G rises through the filling-neckand shows the quantity of oil in the fount.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is

1. The combination, with a lamp fount and burner, of a cap for coveringthe wick-tube, a rod for holding the cap from the wioletube, a floatthrough which said rod loosely passes, and devices for locking the rodon the float at any desired point of the rod, substantially as hereinshown and described.

2. The combination, with a lamp fount and burner, of a cap covering thetop of the wick tube, a weight or spring acting on the said cap, a rodfor holding the cap off of the wicktube, a float in the fount, throughwhich float the rod loosely passes, and of mechanism for locking thefloat on the rod at any desired tube, the lug N on the cap, anda weightor spring acting on the cap, substantially as herein shown anddescribed.

4. The combination, with a lamp-fount, a burner, a pivoted cap providedwith a lug, N, and a weight or spring for actuating the said cap, of thefloat 0, provided with the aperture D, the spring E, rod H, and thehandle J, on the upper end of the said rod, substantially as hereinshown and described.

5. The combination, with a lamp-fount, of a burner, the pivoted cap M,the rod H, having its lower part flattened, the float O, the spring E,and a spring or Weight for actuating the cap, and projections or catcheson the cap, which projections or catches can engage the rod H,substantially as herein shown and described.

6. The combination, with alamp-fount, ofa burner, the pivoted cap M, aweight or spring for actuating the same, the float G,having the apertureD, the funnel F, the spring E, the rod H, and catches or projections onthe cap for engaging the rod H, substantially as herein shown anddescribed.

7. The combination, with the fount A, of the rods 13, the float O, aburner on the fount, the cap M, the rod H, a spring for locking the rodon the float, and projections on the. cap M, which projections canengage the rod H when raised, substantially as herein shown anddescribed.
